Learning Objective

To develop students' iterative designing and problem solving capability by:

  • designing a chair frame structure within the stated constraints
  • choosing appropriate sizes for the various parts of the frame structure and the seat
  • choosing appropriate joining methods for the various parts of the frame structure.

Design Brief

Design a wooden chair frame structure.


  • The top of the seat must be 460mm above the floor.
  • The chair structure must be a rigid frame structure made from wood.
  • The chair frame structure must have four legs, a seat and a back rest.
  • The chair seat must be fixed to the chair structure.
  • The finished design must be safe to use.

An image showing the Flash animation logo SWF Flash logo is a link to a Flash animation.

Flash animations are embedded into the pages of all my D&T Modules but there are pictorial links to the animations on this web site so that devices that cannot play Flash animations will at least show a jpeg screenshot of the animation.
